The qBittorrent integration was passing only { limit } to listTorrents(),
which returns completed torrents first by default. With a 50-item limit and
large completed torrent libraries, active/incomplete torrents never appeared
in the response. The widget's client-side showCompletedTorrent filter then
had nothing to display.
Adding sort: 'progress' (ascending) ensures incomplete/active torrents always
appear first, even with a low limit.
